Multi-Layered Pillow Cover

ABSTRACT

A semiconductor device includes a first layer, first and second active areas disposed on the first layer; a trench disposed between the first and second active areas, an insulating oxide that fills the trench to a level below a surface of the first and second active layers, and a nitride cap disposed on top of the insulating oxide so that the first and second active areas can be cleaned without damaging the insulating oxide. A top surface of the nitride cap in regions adjacent to the first and second active areas is aligned with a top surface of the first and second active areas, a top surface of the nitride cap in a center region of the nitride cap is stepped below the top surface of the adjacent regions, and a void is formed between the top surface regions adjacent to the first and second active areas.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to a pillow sheet and more specificallyto an assembly of multi-layered pillow sheets.

2. Description of Related Art

Pillow cases are used by every household for covering pillows to preventpillows from being soiled so that pillows do not need to be cleanedfrequently. But even pillow cases get soiled from sweat, drool, and oilssecreted from the face or hair. Most of the time, a household won'tchange and wash pillow cases every day because the pillow cases need tobe removed from the pillows for washing and put back on after washing.Therefore, pillow cases are used for a while until the household hastime for laundry, normally during the weekend. The soiled pillow casesare not healthy to skin. Sometimes, the soiled pillowcases have anunpleasant smell. It is not pleasant to sleep on a pillow case that hashair left on it either. But to replace pillow cases and clean them everyday is troublesome and tedious. Therefore, it is necessary to have aproduct that can conveniently provide fresh smell, clean, smooth pillowsheet everyday without causing inconvenience and trouble.

SUMMARY OF THE INVENTION

One object of the present invention is to prevent acne. The idea is tohave a fresh sheet each night which is good for skin care and will helpprevent the development of face pimples.

Another object of the all satin pillow cover invention is to have nowrinkles on the face from sleeping on a crumpled sheet and to preventbed hair.

The present invention is a multi-layered pillow cover assembly whichincludes an attachment that wraps around the pillow. The pillow coverassembly has a plurality of fresh sheets that can be turned like thepages of a book in the morning so as to allow a fresh new sheet to beexposed for the next night's sleep experience. The sheets for oily andcombination skin are made of a layer of cotton on top stitched into apolyester sheet underneath. The cotton is able to absorb oils from onesskin and the polyester prevents oils from the skin from seeping throughto the next sheet. The pillow sheets for dry skin and T-zone combinationskin are made of satin polyester. The new sheet every day preventspimples and the satin helps prevent wrinkles and bed hair.

The more important features of the invention have thus been outlined inorder that the more detailed description that follows may be betterunderstood and in order that the present contribution to the art maybetter be appreciated. Additional features of the invention will bedescribed hereinafter and will form the subject matter of the claimsthat follow.

Before explaining at least one embodiment of the invention in detail, itis to be understood that the invention is not limited in its applicationto the details of construction and the arrangements of the componentsset forth in the following description or illustrated in the drawings.The invention is capable of other embodiments and of being practiced andcarried out in various ways.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, there is disclosed a pillow cover assemblyaccording to one embodiment of the present invention. FIG. 1 shows theback of the pillow cover assembly 10 around a pillow 20 and it isattached to the pillow 20 using a pair of straps 12 which have fabrichook and loop fasteners 13 such as Velcro at their ends.

FIG. 2 is a front view of the pillow cover assembly 10 of the presentinvention. As shown in FIG. 2, the pillow cover assembly 10 has aplurality of layers of pillow sheets 11. Said layers of pillow sheetsare rectangular in shape and have two short edges and two long edges.Said layers of pillow sheets are held together on one of the short edges14 and thus said layers of pillow sheets can be flipped around the shortedge 14 like a book. The layers of pillow sheets may be bound togetherby sewing, or by other suitable fastening means. The pillow coverassembly 10 further comprises an attachment system 12 used to attach thepillow sheets 11 to a pillow 20 or a pillow case configured to house thepillow. Preferably, there are five to seven sheets 11 that can be turnedeach morning so that the user has a fresh pillow sheet for his or herhead each night of the week. Once the five or seven sheets have beenflipped the pillow cover assembly is removed from the pillow, washed andreused. The attachment system may include a pair of straps 12 and anysuitable fastening means 13 at one end of each of straps. The fasteningmeans may include not limited to fabric hook and loop fasteners such asVelcro hook and loop.

Each layer of sheets 11 is approximately 18 inches wide and 24-31 incheslong. In one embodiment, each sheet is one inch longer than the onebelow so there is a space that a user can have for ease of turning eachused sheet 11 over to expose the new fresh pillow sheet. The sheets 11are made of soft and smooth materials, such as polyester satin or silksatin or mulberry silk satin—a very high end silk material, so that theyare good for skin care and will help prevent the development of facewrinkles or pimples. Each sheet for oily skin is made of a layer of softcotton on the top and polyester is attached on the bottom.

FIG. 3 illustrates how the sheets 11 can be flipped upon lifting up fromthe pillow. The used and soiled layer of sheet 11 is lifted up andflipped over around the bound end 14 so as to expose a new and freshlayer of pillow sheet.

FIG. 4 is a stand-alone pillow covering 30 that has a bit of a frill 31on the edge of it for decoration. Satin pillow covering 30 is used ontop of the pillow sheets 10.
